Scalp hematoma surgery is usually not dangerous, but generally scalp hematomas do not need to be treated surgically, as directed by your doctor.
A scalp hematoma is formed when a blood vessel ruptures while the scalp remains intact after a blunt blow or collision to the head. Subcutaneous hematoma has no fluctuation, the periphery is harder than the center, and is more limited. This hematoma can be absorbed by itself, and generally does not need to be treated.
Subcapillary hematoma is large in scope, with obvious fluctuation and soft to touch. Large hematoma can be aspirated by puncture and then put pressure bandage; small hematoma can be directly put pressure bandage and self-absorbed. Small hematoma can be absorbed by direct pressure bandage. Infected hematoma requires incision and drainage.
Subperiosteal hematoma with high tension may have fluctuation, and the scope is larger. The treatment is the same as that of subcapsular hematoma. However, if it is accompanied by skull fracture, pressure bandage should not be applied to avoid aggravation of the condition.
In the event of scalp hematoma, please go to the hospital as soon as possible, under the guidance of professional doctors for treatment and recovery.
